Dear All,

I conduct a multiphase analysis of tablets from food-pharma industry.

I am looking for the thermal-mechanical properties of any pharmaceutical tablet, a chew gum, or similar.

Specifically, I am looking for:
- Density (kg/m3)
- Specific heat (j/kg k)
- Thermal conductivity (w/m k)
- Viscosity (kg/m s)
- Molecular weight (kg/kg mol)
- Standard state enthalpy (j/kg mol)

I searched several material databases (they usually contain pure materials like steel, etc.), a number of scientific articles, etc.

I found only info on the density that it often ranges between 1000-1500(kg/m3).
I also found that some ingredients of some tablets have the thermal conductivity approx. 750(w/m k).

Please help.
Regards

For pharma tablet you may search not active substance (they differ from pill to pill) but base/filler. Some common fillers are: lactose, starch, dibasic calcium phosphate, mannitol.

@Karachun
Thank you for your feedback.

It is an idea to look for thermal-mechanical properties of the most common ingredients.
